Jakarta. An earthquake measuring 6.4-magnitude on the Richter scale rocked Bali on Wednesday morning (22/03). No tsunami alert was issued by authorities.
The quake occurred at 07.11 a.m. local time. Its epicenter was detected 23 kilometers southeast of Denpasar, the capital of the province of Bali, at a depth of 117 kilometers.
Strong tremors were felt in the districts of Kuta and Tabanan in Bali and in Mataram in the neighboring island of Lombok, West Nusa Tenggara, according to National Disaster Mitigation Agency (BNPB) spokesman Sutopo Purwo Nugroho.
"In Denpasar, tremors were felt for at least five seconds. Many residents fled their homes. Windows on houses rattled and parked cars were shoved around," Sutopo said.
"There were two separate tremors. The second one was stronger," he added.
Residents in the Bali districts of Badung, Tabanan, Klungkung, Gianyar, Karangasem, Singaraja, Bangli and Buleleng also reported slight tremors.
Weaker tremors were also reported in Banyuwangi, a district in East Java closest to the island of Bali.
Sutopo said a 3.9-magnitude aftershock followed the quake, which was triggered by tectonic activities between the Indo-Australia and Eurasia plates.
Residents in Bali have been advised to stay calm and only rely on information issued by authorities.
